Throughout history, the castle took on various forms, the style of the building changed, and the Germans decided to restore its original Gothic character. These works were entrusted to the German conservator of monuments, Konrad Steinbrecht, and after 20 years of conservation work, the rebuilt High Castle was officially opened. Steinbrecht managed the reconstruction of the Middle Castle and the Lower Castle only until 1921 when he retired. A museum began to function in the castle, where you could see exactly how the Teutonic Knights lived. It was as realistic as if the inhabitants had just left the place.
